v5.5 [Sep 14, 2013]
- Fixed: Autopilot NAVSRC lost messages which caused the autopilot to drop down from NAV to TRK or HDG mode.
- Fixed: Autopilot altitude hold that was offset by tens of feet from the desired target. Existing altitude offsets may take a few minutes of straight/level AP flight to self-calibrate out.
- Improved: Autopilot tolerance of EFIS installations that contain higher than ideal vibration levels.
